Waveshare RP2350 powered rounded LCD also comes with a rounded metal case

Waveshare has recently launched RP2350-LCD-1.28, an RP2350 rounded LCD development board with a 240×240 pixel resolution and a 65K-color IPS panel. Built around the Raspberry Pi RP2350 chip, this development board features 520KB of SRAM, 4MB of flash memory, and a Type-C connector for easy programming and power.

Other features include a rechargeable Lithium battery manager, 6-axis IMU with a 3-axis gyroscope and accelerometer, multiple GPIO pins (30 in total), USB 1.1 host/device support, temperature sensor, and 24 PWM channels, all configured for flexible I/O options. These features make this device suitable for IoT devices, wearable tech, and embedded applications requiring a compact, energy-efficient microcontroller with display capabilities.

Previously we have written about various types of display development boards including the Waveshare 11.6-inch Capacitive Touch Display, the ESP32-S3-AMOLED-1.91-M dev board, the LOLIN S3 Mini Pro V1.0.0 and many more feel free to check those out if you are looking for unique display based products.
